Research On Risk Management Of Metro Construction Based-on Owner

Due to its own characteristics and mixed construction market, metro construction makes the owner undertake many risks from the natural environment, social environment, organizational environment, and other aspects in the process of construction. In practice, the implementation of risk management is often scattered in various stages of construction projects, and each participating unit carries out risk management within its own contract scope, making the entire project risk management be in the temporal segmentation and spatial dispersion state. This paper, from the perspective of the owners, systematically investigate the integrated risk management system of the metro construction project, in order to encourage owners standardize risk management processes and methods systematically and comprehensively, and fully integrate the resources and advantages of project members to build a unified platform for risk management.This paper focuses on the following aspects and obtains the corresponding results.1. With the metro construction characteristic as objective basis, with risk management theory, life cycle management theory and organizational theory as the theoretical basis, and with the owners be the core position in risk management as the rationale basis, the Owner-based Integrated Model of Risk Management (OIRM, for short) is made. Three-dimensional system of the risk dimension-organization dimension-process dimension of risk management is the core of this model. The continuous and systematic risk management paradigm for metro construction is also formed in this paper.2. WBS matrix will be introduced to OIRM, to regulate the decomposition ideas and methods of OIRM process dimension, this paper will illustrate this combined with a bid planning of a metro line 2.3. With Bell model as the theory, to build owners integrated risk management organization platform layer, and to analyze the cooperation strategy of risk management organization members with asymmetric evolutionary game theory, and the model combined objective evaluation and subjective evaluation to assess the contractor risk management capabilities is build.4. This paper defines the basic process of risk identification of OIRM, and through literature reviews, expert interviews, work practices and other means identifies the systemic risks of metro construction and the non-systematic risks of investigation phase, design phase, bidding phase and construction phase comprehensively and systematically.5. This paper proposes the OIRM risk assessment system, and builds the risk assessment model based on risk natural attribute index and management capability index, and determines the important parameter (the index S* of social average advanced risk management of metro construction industry) of the assessment model by using questionnaire.6. This paper expounds the application of the risk allocation principles from the aspects of risk allocation beforehand and risk allocation afterwards; then gives metro construction risk strategy ideas on each stage, and put forward the framework of OIRM model risk precaution system.This study broadens the perspective of risk management research, further deepens the theory system of integrated risk management and expands the application level of integrated risk management.
